IPM NEWS --- international IPM news and programs

I. IPM NEWS / APPLICATIONS international IPM news and programs BIOSCIENCE Debates Biocontrol Specificity In the preface to a profound 52-page special section in the June 1996 issue of BIOSCIENCE (vol. 46, no. 6), editor R. Chasan observes that, "The challenge of embarking on biological control programs is to develop ways to assess the host specificity of biological control agents and to predict the chances that an apparently specific biological control agent will evolve the ability to harm a previously nontarget species." Six insightful articles, a "roundtable" summary, and full color photos address the crucial biocontrol issue of host specificity. Titles range from the theme establishing "Host Specificity and Biological Control," by P.B. McEvoy, through microbe-to-microbe interactions, insect parasitoids and predators, to D. Secord and P. Kareiva's summation, "Perils and Pitfalls in the Host Specificity Paradigm," which presents an interesting table of cases where, for some reasonpossibly evolution, an original interaction has caused an "evolved host shift."

To judge from the extended space allotted this special section, The American Institute of Biological Science (AIBS), BIOSCIENCE publisher, clearly attaches importance to the topic and its relevance to the future directions of pest management and environmental stewardship.

IPM Improves the Bottom Line A study comparing "conventional" and IPM production costs for sweet corn (_Zeaspp.) in the northeastern U.S. reveals a 34% advantage for the later, according to the recently published NORTHEAST SWEET CORN PRODUCTION AND INTEGRATED PEST MANAGEMENT MANUAL, edited by R.G. Adams and J.C. Clark. Reduced usage of pesticides under the IPM regime helped generate several advantages, including that of increased financial returns per acre (hectare).

This 120-page, 21-chapter, extensively illustrated publication presents a thorough examination of the topic ranging from discussions of sweet corn plant physiology, requirements, and production techniques, to a comprehensive, detailed analysis of the key groups of pests attacking this crop and how best to manage them. Other sections address pesticide application equipment, pesticide safety, and groundwater protection.

This attractively designed softbound manual contains 4-color plates throughout, including outstanding drawings of grass weeds. It was produced in 1996 by the Univ. of Connecticut (USA) and the Cooperative Extension System, and is numbered 95-18.

Caribbean Nations Urged to Adopt IPM Representatives from 12 Caribbean nations participated in a late 1994 workshop for SETTING UP AN INTEGRATED PEST MANAGEMENT NETWORK FOR THE CARIBBEAN," and strongly recommended that "the governments of the region take immediate steps to establish IPM as national policy in agriculture, health, and the environment," according to the recently published proceedings of the event. Impetus for establishing a Caribbean IPM network originated with several sources spearheaded by the Caribbean Agricultural Research and Development Institute (CARDI), and the Technical Centre for Agricultural and Rural Cooperation based in the Netherlands. The U.K.-based International IPM Working Group also was involved.

The Workshop collectively urged that IPM training, identification of IPM expertise, collection of relevant information, and opening lines of communication be pursued.

The first issue of a newsletter, IPM NETWORK FOR THE WIDER CARIBBEAN, was published in June 1996 and copies are available, as are a limited number of copies of the workshop proceedings FMI: J.C.

Global Weed Biocontrol Importance Grows A record number of participants at the IX International Symposium on Biological Control of Weeds, held during 1996 at the Univ. of Stellenbosch (South Africa), underscored the increasing importance and complexity of this meeting, held every fourth year. Over 200 delegates (compared with 181 at the VIII Symposium in new Zealand, 1992) presented papers and posters and represented 91 organizations from 25 countries, according to the Symposium's secretariat. The formal program was divided into seven sessions comprised of 83 lectures, which ran sequentially, and 61 posters. The III International Bioherbicide Workshop preceded the Symposium. Workshop topics ranged from project reports and regional updates to market assessment and commercialization.

The symposium Proceedings (including all the papers from the Bioherbicide Workshop) were published in July 1996 and cover all aspects of the theory and practice of the biological control of terrestrial and aquatic weeds using plant-feeding insects and plant pathogens as biocontrol agents. Since no journal is devoted exclusively to this topic, these recorded proceedings represent the most comprehensive record of international weed biocontrol research.

IPM MEDLEY --- publications and other IPM information resources

II. IPM MEDLEY general information, publications of interest, and other information and resources related to IPM Barrier System Helps Control Rodents Agricultural engineers at the International Rice Research Institute (IRRI) in the Philippines have developed a highly effective rodent control system that requires no baits or poisons, no electricity, no nightime personnel patrols, uses locally available materials, and relies on the rice crop itself to attract the targeted rice rats. Engineering consultant G.R. Quick, in an article in PEST MANAGEMENT FOCUS, describes the `active barrier' system for rice rat control as "an easily erected plastic fence punctuated at regular intervals by holes, each of which opens into a mass trap." Particularly during the night hours the rodents smell the rice crop, run along the 30 cm (1 ft) high, or higher barrier until finding one of the funnel-shaped openings located 5-30 m (16-98 ft) apart, enter, and cannot escape. Once caught in the traps, the rats can be disposed of.

Experiments at IRRI over several years found that the rats did not chew on the plastic, nor jump over or burrow under the fence under normal conditions. As many as 15 rats have been caught in one trap during a single night. Mr. Quick points out that costs per unit area to erect the re-usable barrier system decrease as the area enclosed increases. It is not uncommon for rats to cause 50-100 percent crop loss, so barrier costs may be recovered in many cases. If handled carefully, the materials can be removed, stored, and re-erected.

Credit for the basic idea, Quick points out, belongs to farmers in Malaysia and researchers at the Malaysian Agricultural Research and Development Institute. The idea was refined and tested at IRRI. FMI: G.R. Quick, 292 David Low Way, Peregian Beach, Qld. 4573, AUSTRALIA Fax: 61-74-48-2174

A Revised Study of Crop Losses In 1967, H.H. Cramer published PLANT PROTECTION AND WORLD CROP PRODUCTION based on the premise that an `ability to feed a growing world population is impossible without effective means of crop protection.' Nearly three decades later a team of German scientists, with extensive input from around the world, expanded the original Cramer study, added extensive new data, and produced the highly readable, important work, CROP PRODUCTION AND CROP PROTECTION, ESTIMATED LOSSES IN MAJOR FOOD AND CASH CROPS. This ambitious study by E-C. Oerkeet al published in 1994, not only cites the expanding pressure on agricultural production to meet burgeoning needs, but devotes a chapter to the development and changes that have occurred in crop protection pests' increasing resistance to chemicals, environmental concerns, and other emerging challengesand the implications these factors hold for the future.

A series of sections comprising the bulk of the 815-page, hardbound volume present estimates for pest-caused crop losses in eight major crops in key growing areas worldwide. Among the uses of crop loss information the authors note, is "Translating the concept of integrated pest control into reality."

For the future, "Integration of all biological measures will be the most important" approach for intensification of crop production, the authors assert. They also state that, "The desire to achieve integrated control is as old as the concept of pest control itself," referring to appropriate crop rotations, cultural techniques, and use of suitable resistant varieties, among other practices.

Not all the theories advanced in this work will meet with complete agreement, particularly regarding weed management. But on balance, the depth of crop loss information and the relationships between pests, crop plants, yields, and production pressure ensure that the text is a milestone in crop protection literature.

IPM RESEARCH/TECHNICAL PAPERS --- categories and topics related to IPM

III. RESEARCH REVIEW research and findings related to IPM. Chemistry and IPM Papers presented at the 5th European Conference on Chemistry and the Environment (May 1995) have been collected and published as a "Special Issue on Pesticide Chemistry for Sustainable Agriculture," in the JOURNAL OF ENVIRONMENTAL SCIENCE AND HEALTH, PART B (vol. 31, no. 3, 1996). Not all the papers have a direct relationship to IPM, but several may be of interest, such as: "Sustainable Agriculture and the Use of Pesticides," Kiraly; "Biocontrol of Weeds: Overcoming Evolution for Efficacy," Gressel, et al; "Biopesticides: Has Their Time Come?," Menn; "Application of Natural Oil in IPM of Grapevine with Special Regard to Predatory Mites," Kiss, et al; and, "Risk Reduction in Pesticide Development in Developing Coun tries - Challenges and Opportunities," Sugavanam. Narrowing the IPM Concept Weed scientists have narrowed the IPM concept to a single group of pestsweedsand begun using the phrase "integrated weed management." A recent issue of WEED SCIENCE presents key papers from a symposium devoted to integrated weed management. Topics ranged from discussion of development, through successes, to a future view, "Weed Science Beyond the Weeds: The Role of Integrated Weed Management (IWM) in Agroecosystem Health," by Swanton and Murphy. The issue containing the papers is 44(2), April-June 1996.
